level-post

get consistent post hooks for leveldb.

travis

testling

var level = require('level')

var db = level('/tmp/whatever-db')

post(db, function (op) {
  //this is called after every put, del, or batch
  console.log(op)
})

db.put('foo', 'bar', function (err) {
  //...
})

methods

post(db, opts={}, cb)

Create a hook to listen for database events matching the constraints in opts. cb(op) fires for each matching operation for op, an object with type, key, and value properties.

You can use these keys as constraints, just like level core:

  • opts.gte, opts.start, opts.min - greater than or equal to
  • opts.gt - greater than
  • opts.lte, opts.end, opts.max - less than or equal to
  • opts.lt - less than

You can also specify a keyEncoding with opts.keyEncoding. If there was a keyEncoding set up by leveldb in the constructor (at db.options.keyEncoding), that one will be used.
